i need help with a big part with iterative

Hey guys
so i have this big part, that the datums are defined by 3 datums points (three holes with sample hits that i did iterative with). I then constructed three theorietical planes (alignment planes) and defined those as ABC. Then i measured all the different features on the parted and called them out using FCF position.
the program works well, but some of my results gets weirdly high.
Ill upload pics with the datum targets (see black circles)

  • IMO, measure the 3 holes with sample hits. Use all 3 for level, use the 2 'co-axial' for rotate, and a mid-point of the 'co-axial' for the origin. IF they all have one common axis value (say, all at the same "Z" value) construct a plane from them. If the 'co-axial' holes have 2 common axis values (say, Y & Z) construct a 3D line of them and a mid-point. LEVEL plane, ROTATE line, XYZ origin to the mid-point.
